All FLEXXCEL materials have a chemical barrier film to protect the fiberglass substrate and minimize porosity. The chemical barrier component of these materials is in the form of a film that is laminated to the fiberglass cloth.

FLEXXCEL MD4 and HD4 = FOR DRY SERVICE

LFP CrossFilm based chemical barriers are
laminated to the coated fiberglass. The use of LFP CrossFilm Chemical Barriers provides superior protection in corrosive environments.

A zero porosity chemical barrier is the most critical component for preventing chemical attack.

FLEXXCEL MD7, HD7, HD12, and HD20 = FOR WET SERVICE

FLEXXCEL HT series fabric belts rated for temperatures up to 1000°F. Insulation is bonded to FLEXXCEL HD4 material to prevent hot gas from residing between the two components.

Extends like of insulation component.

Prevents insulation from falling into duct.

Makes installation of high temperature composite belts easier.

A zero porosity chemical barrier is the most critical component for preventing chemical attack.

FLEXXCEL HT1, HT3, and HT5 = FOR HOT-DRY SERVICE

Flexxcel Fluoroplastic Belt Materials

Fluoroplastic materials have been successfully used in challenging expansion joint applications since the early 1980's. The expansion joint fabric is composed of two components— PTFE resins and fiberglass cloth. The fiberglass is used to give the fabric strength. The fiberglass can be of varying weights to give the fabric material the necessary tensile strength. The fiberglass alone is susceptible to degradation from chemicals and liquids. By thoroughly coating all surfaces of the fiberglass filaments, a strong and flexible base material is created. This base material can then be laminated to a PTFE film (Chemical Barrier) of varying thickness to provide a non-porous and chemically inert gas seal. Its virtual inertness to most chemicals make it an excellent choice for applications in wet corrosive environments.
